Description

A beauty device handle and skin management system with ultrasonic and cooling technologies Technical Field

[0001] This application relates to the field of beauty instrument technology, and in particular to a beauty instrument handle and skin management system incorporating ultrasonic and cooling technologies. Background Technology

[0002] A cooling beauty gun plays an important role in the beauty process, used for skin care such as calming and soothing the skin, shrinking pores, and promoting the absorption of skin care products.

[0003] However, most beauty guns currently on the market that provide a cooling sensation use a semiconductor cooling chip combined with a metal probe to achieve the cooling function. However, due to the limited power of the cooling chip and the unreasonable design of the heat dissipation structure, the penetration and durability of the cooling sensation of the ultrasonic probe are weakened, making it difficult to meet the needs of users.

[0004] In addition, commercially available beauty guns generally focus on single cold / hot compress or basic vibration functions, lacking synergistic applications with other beauty techniques. Summary of the Invention

[0005] Therefore, it is necessary to provide a beauty device handle and skin management system with ultrasonic and cooling technologies to address the aforementioned problems with existing beauty guns.

[0006] The first aspect of this application provides a beauty device handle with ultrasonic and cooling technologies, the beauty gun comprising:

[0007] The housing includes an ultrasonic probe and a handle, the ultrasonic probe and the handle forming a mounting cavity;

[0008] A refrigeration device is located inside the mounting cavity. The refrigeration device includes a cooling guide, a refrigeration element, and a radiator. The refrigeration element is disposed between the cooling guide and the radiator. The cooling guide includes a first cooling section and a second cooling section connected to each other. The length of the second cooling section extends along the length direction of the handle.

[0009] An ultrasonic module is mounted on the ultrasonic probe.

[0010] This application discloses a beauty device handle incorporating ultrasonic and cooling technologies. Both the cooling device and the ultrasonic module are installed within a mounting cavity formed by the ultrasonic probe and the handle. The cooling device includes a cooling conductor, a cooling element, and a heat sink. The cooling element is located between the cooling conductor and the heat sink. The cooling element conducts its generated cooling energy to the ultrasonic probe through the cooling conductor, reducing the surface temperature of the ultrasonic probe and creating a cooling effect. Simultaneously, the cooling element releases heat through the heat sink to ensure its normal operation. The cooling conductor includes a first cooling section and a second cooling section connected to each other. The second cooling section extends along the length of the handle, making the cooling conductor sufficiently long within the limited space of the mounting cavity. This increases the contact area between the cooling surface of the cooling element and the cooling conductor, improving cooling efficiency and resulting in a better cooling effect. This application, based on the coordinated operation of the cooling conductor, cooling element, and heat sink, rationally utilizes the internal space of the beauty device to enhance the cooling effect of the ultrasonic probe, providing users with a better user experience.

[0011] In one embodiment, the cooling element is a semiconductor cooling chip structure, with the cooling surface of the cooling element facing the second cooling conductive part and the heat dissipation surface of the cooling element facing the heat sink.

[0012] The beauty device handle with ultrasonic and cooling technology in the above embodiments achieves the cooling function by using a semiconductor cooling chip structure for the cooling element. The semiconductor cooling chip has the advantages of not requiring the complex structure of a traditional compressor, being small in size and light in weight, and is suitable for integration into the narrow cavity of the beauty gun, improving portability and comfort when using it by hand. In addition, the semiconductor cooling chip can precisely control the cooling temperature by adjusting the magnitude and direction of the current, meeting the needs of different skin types or care.

[0013] In one embodiment, the ultrasonic probe is made of titanium alloy.

[0014] The beauty device handle with ultrasonic and cooling technology in the above embodiment has an ultrasonic probe made of titanium alloy. The ultrasonic probe reduces the loss of ultrasonic waves emitted by the ultrasonic module, improves the transmission efficiency, and the ultrasonic waves travel quickly on the titanium alloy material.

[0015] In one embodiment, the heat sink is an elongated block structure, and the length extension direction of the heat sink is consistent with the length extension direction of the cooling element.

[0016] The beauty device handle with ultrasonic and cooling technology in the above embodiment features a long, strip-shaped heat sink. Since the length of the heat sink extends in the same direction as the second cooling section, the contact area between the heat sink and the cooling element is sufficiently large, improving the heat sink's heat absorption capacity and thus enhancing heat dissipation efficiency. Furthermore, the elongated shape of the second cooling section, the cooling element, and the heat sink effectively utilizes the limited space of the mounting cavity, optimizing both cooling and heat dissipation.

[0017] In one embodiment, the radiator has a liquid channel and an inlet and an outlet connected to the liquid channel, and both the inlet and the outlet are configured to be connected to an external water source.

[0018] The beauty device handle with ultrasonic and cooling technology in the above embodiment dissipates heat through a water-cooling radiator. Compared with natural cooling, water-cooling has higher heat dissipation efficiency, and water-cooling has lower operating noise compared with air cooling.

[0019] In one embodiment, the surface of the heat sink is provided with a plurality of spaced-apart fins.

[0020] The beauty device handle with ultrasonic and cooling technology in the above embodiment has multiple spaced fins on the heat sink surface, which allows heat to be transferred to the air more quickly. Moreover, the multiple fins can prevent heat from accumulating in local areas and ensure that heat is evenly diffused to all fin surfaces.

[0021] In one embodiment, a control circuit board is further included, which is installed in the mounting cavity and electrically connected to the ultrasonic module and the cooling element. The control circuit board is located on the side away from the heat sink, and the second cooling conduction part is located between the control circuit board and the cooling element.

[0022] The beauty device handle with ultrasonic and cooling technology in the above embodiment has a second cooling section located between the control circuit board and the cooling element. This allows the cooling energy generated by the cooling element to be transferred to the control circuit board through the second cooling section, thereby dissipating heat from the control circuit board and ensuring its reliable operation.

[0023] In one embodiment, the control circuit board is elongated, and the length extension direction of the control circuit board is consistent with the length extension direction of the second cooling section.

[0024] The beauty device handle with ultrasonic and cooling technology in the above embodiment has a long strip-shaped control circuit board, and its length extension direction is consistent with the length extension direction of the second cooling part. This increases the relative area between the second cooling part and the control circuit board, improves the heat dissipation effect of the second cooling part on the control circuit board, and the long strip-shaped control circuit board is better adapted to the space of the mounting cavity.

[0025] In one embodiment, the first cooling section and the second cooling section are distributed sequentially along the direction of the ultrasonic probe toward the handle, and the first cooling section has an avoidance groove whose shape is adapted to the shape of the ultrasonic module.

[0026] The beauty device handle with ultrasonic and cooling technology in the above embodiment has a cooling guide distributed along the length of the beauty gun. The first cooling guide is located on the side of the mounting cavity near the ultrasonic probe. By having the first cooling guide adhere to the inner wall of the ultrasonic probe, the surface temperature of the ultrasonic probe can be reduced more effectively, providing the user with a better cooling effect. At the same time, the first cooling guide has a relief groove that matches the shape of the ultrasonic module. This not only allows the first cooling guide to better adhere to the inner wall of the ultrasonic probe, but also prevents the ultrasonic module from directly contacting the first cooling guide, as the vibration of the ultrasonic module can affect the normal operation of the cooling element through the cooling guide.

[0027] In one embodiment, a temperature sensing element is also included, which is located within the mounting cavity and close to one end of the ultrasonic probe, and is used to measure the temperature at the ultrasonic probe.

[0028] The second aspect of this application provides a skin management system, including the beauty device handle with ultrasonic and cooling technologies as described in any of the preceding claims. Attached Figure Description

[0038] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0039] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate for the embodiments of this application described herein.

[0040] As shown in Figures 1-4, this embodiment provides a beauty device handle with ultrasonic and cooling technology. The beauty gun includes:

[0041] The housing 10 includes an ultrasonic probe 11 and a handle 12, with the ultrasonic probe 11 and the handle 12 forming a mounting cavity 101.

[0042] The refrigeration device 20 is located in the mounting cavity 101. The refrigeration device 20 includes a cooling guide 21, a cooling element 22, and a radiator 23. The cooling element 22 is disposed between the cooling guide 21 and the radiator 23. The cooling guide 21 includes a first cooling part 211 and a second cooling part 212 that are connected to each other. The length of the second cooling part 212 extends along the length direction of the handle 12.

[0043] Ultrasonic module 30 is installed on ultrasonic probe 11.

[0044] The beauty device handle with ultrasonic and cooling technology disclosed in this application has a cooling device 20 and an ultrasonic module 30 both installed in a mounting cavity 101 formed by the ultrasonic probe 11 and the handle 12. The cooling device 20 includes a cooling conductor 21, a cooling element 22, and a heat sink 23. The cooling element 22 is located between the cooling conductor 21 and the heat sink 23. The cooling energy generated by the cooling element 22 is transferred to the ultrasonic probe 11 through the cooling conductor 21, reducing the surface temperature of the ultrasonic probe 11 and thus creating a cooling effect. While cooling, the cooling element 22 also releases heat through the heat sink 23 to ensure the normal operation of the cooling element 22. The cooling conductor 21 includes a first cooling part 211 and a second cooling part 212 that are connected to each other. The second cooling part 212 extends along the length of the handle 12, making the cooling conductor 21 long enough in the limited space of the mounting cavity 101, thereby increasing the contact area between the cooling surface of the cooling element 22 and the cooling conductor 21, improving the cooling efficiency, and thus obtaining a better cooling effect. This application, based on the cooperation of the cooling component 21, the cooling element 22, and the radiator 23, makes reasonable use of the internal space of the beauty gun, improves the cooling effect of the ultrasonic probe 11, and provides users with a better user experience.

[0045] A connecting seat 13 may be provided between the ultrasonic probe 11 and the handle 12. The connecting seat 13 is movably connected to the ultrasonic probe 11 and the handle 12 respectively. Specifically, the connecting seat 13 can be connected to the ultrasonic probe 11 and the handle 12 respectively by means of buckle, threaded connection, magnetic attraction, etc.

[0046] The ultrasonic module 30 can achieve a variety of skin care effects by generating high-frequency vibrations. The ultrasonic module 30 can be installed in the mounting cavity 101, and the ultrasonic module 30 can be distributed at one end close to the ultrasonic probe 11 to avoid the energy of the emitted ultrasonic waves being dispersed due to the distance between the ultrasonic module 30 and the user's skin, thus reducing the skin care effect.

[0047] The cooling device 20 can be used to reduce the surface temperature of the ultrasonic probe 11. The cooling device 20 may include a cooling conductor 21, a cooling element 22, and a heat sink 23. The cooling element 22 can operate by electronic cooling or semiconductor cooling. When the cooling element 22 is working, there is a process of heat absorption and heat release. Through the close contact between the cooling surface of the cooling element 22, the cooling conductor 21, and the ultrasonic probe 11, the cold energy generated by the cooling surface of the cooling element 22 is transferred to the ultrasonic probe 11 through the cooling conductor 21, thereby reducing the surface temperature of the ultrasonic probe 11. At the same time, because the heat release surface of the cooling element 22 is in close contact with the heat sink 23, the heat sink 23 quickly absorbs the heat on the cooling element 22 for heat dissipation.

[0048] The cooling component 21 can be a metal or non-metal material with high thermal conductivity. For example, the cooling component 21 can be a high thermal conductivity metal such as copper or aluminum, or a graphene ceramic composite material. Preferably, the cooling component 21 is made of copper. The cooling component 21 may include a first cooling part 211 and a second cooling part 212. The second cooling part 212 may extend along the length of the handle 12, so that the second cooling part 212 is adapted to the shape of the handle 12, ensuring that the second cooling part 212 is long enough. Correspondingly, the cooling element 22 and the corresponding heat sink 23 can be adaptively adjusted according to the shape and size of the second cooling part 212, so that the cooling element 22 and / or heat sink 23 can be large enough within the space limitation of the mounting cavity 101, thereby improving the ability of the cooling element 22 to transfer cold energy to the ultrasonic probe 11, thereby improving the icy feeling effect on the surface of the ultrasonic probe 11. Additionally, it should be noted that the first cooling section 211 may be located within the mounting cavity 101 near the ultrasonic probe 11. Since the first cooling section 211 and the second cooling section 212 are interconnected, the cooling energy generated by the cooling element 22 is sequentially transferred to the ultrasonic probe 11 via the first cooling section 211 and the second cooling section 212. It should also be noted that the first cooling section 211 and the second cooling section 212 can be an integrally formed structure to improve heat transfer efficiency.

[0049] As shown in Figures 1 and 2, in addition to the features of the above embodiments, this embodiment further specifies that: the cooling element 22 is a semiconductor cooling chip structure, the cooling surface of the cooling element 22 is disposed opposite to the second cooling conduction part 212, and the heat dissipation surface of the cooling element 22 is disposed opposite to the heat sink 23.

[0050] The beauty device handle with ultrasonic and cooling technology in the above embodiment further specifies that the cooling element 22 adopts a semiconductor cooling chip structure to realize the cooling function. The semiconductor cooling chip has the advantages of not needing the complex structure of a traditional compressor, small size and light weight, and is suitable for integration into the narrow cavity of the beauty gun, improving portability and comfort when using it by hand. In addition, the semiconductor cooling chip can precisely control the cooling temperature by adjusting the magnitude and direction of the current to meet the needs of different skin types or care.

[0051] The cooling element 22 can be a strip-shaped sheet structure, and the length extension direction of the cooling element 22 is consistent with the length direction of the second cooling part 212, thereby increasing the contact area between the cooling element 22 and the second cooling part 212 and improving the efficiency of the cooling element 22 in transferring cold energy to the ultrasonic probe 11 through the cooling part 21.

[0052] In addition to the features of the above embodiments, this embodiment further specifies that the ultrasonic probe is made of titanium alloy.

[0053] The beauty device handle with ultrasonic and cooling technology in the above embodiment further specifies that the ultrasonic probe 11 is made of titanium alloy. The ultrasonic probe 11 reduces the loss of ultrasonic waves emitted by the ultrasonic module 30, improves the transmission efficiency, and the ultrasonic waves are transmitted faster on the titanium alloy material.

[0054] As shown in Figure 4, in addition to the features of the above embodiments, this embodiment further specifies that: the radiator 23 has a liquid channel 202, and an inlet 203 and an outlet 204 connected to the liquid channel 202, and both the inlet 203 and the outlet 204 are configured to be connected to an external water source.

[0055] The beauty device handle with ultrasonic and cooling technology in the above embodiment further specifies that the radiator 23 dissipates heat through water cooling. Compared with natural cooling, water cooling has higher heat dissipation efficiency, and water cooling has lower operating noise compared with air cooling.

[0056] The external water source can consist of a water tank and a power pump within the skin management system. Specifically, the water tank is connected to the liquid channel 202 via the power pump, which provides power to form a circulating cooling water path. It should be noted that the liquid channel 202 can be spiral or meandering.

[0057] As shown in Figures 1 to 3, in addition to the features of the above embodiments, this embodiment further specifies that: the heat sink 23 is an elongated block structure, and the length extension direction of the heat sink 23 is consistent with the length extension direction of the cooling element 22.

[0058] The ultrasonic cooling beauty gun in the above embodiment, with its handle incorporating both ultrasonic and cooling technologies, further defines the overall elongated block structure of the heat sink 23. Since the length extension direction of the heat sink 23 aligns with the length extension direction of the second heat-conducting and cold-conducting section 212, the contact area between the heat sink 23 and the cooling element 22 is sufficiently large, enhancing the heat absorption capacity of the heat sink 23 on the cooling element 22 and thus improving heat dissipation efficiency. Furthermore, by making the second heat-conducting and cold-conducting section 212, the cooling element 22, and the heat sink 23 all elongated, the limited space of the mounting cavity 101 is effectively utilized, optimizing both cooling and heat dissipation effects.

[0059] The radiator 23 and the second heat-conducting and cold-conducting part 212 can be fixedly connected by bolts. Based on this, the radiator 23 and the second heat-conducting and cold-conducting part 212 can be tightly attached to the cooling element 22, thereby improving the heat transfer effect among the three.

[0060] As shown in Figures 2 and 3, in addition to the features of the above embodiments, this embodiment further specifies that: the surface of the heat sink 23 is provided with a plurality of spaced fins 231.

[0061] The beauty device handle with ultrasonic and cooling technology in the above embodiment further defines that the surface of the heat sink 23 is provided with multiple spaced fins 231, so that heat can be transferred to the air more quickly, and multiple fins 231 can prevent heat from accumulating in local areas, ensuring that heat is evenly diffused to the surface of all fins 231.

[0062] As shown in Figures 1 to 3, in addition to the features of the above embodiments, this embodiment further includes a control circuit board 40, which is installed in the mounting cavity 101. The control circuit board 40 is electrically connected to the ultrasonic module 30 and the cooling element 22, and the control circuit board 40 is located on the side away from the heat sink 23. The second cooling part 212 is located between the control circuit board 40 and the cooling element 22.

[0063] The beauty device handle with ultrasonic and cooling technology in the above embodiment further defines the second cooling section 212 as being located between the control circuit board 40 and the cooling element 22, so that the cooling energy generated by the cooling element 22 can be transferred to the control circuit board 40 through the second cooling section 212, thereby dissipating heat from the control circuit board 40 and ensuring the reliable operation of the control circuit board 40.

[0064] The control circuit board 40 can be used to control the operating modes of the ultrasonic module 30 and the cooling element 22. For example, the control circuit board 40 can adjust the output power of the ultrasonic module 30 and / or the cooling element 22 according to received user commands or a preset program. For example, the cooling element 22 has multiple operating levels; the control circuit board 40 can receive user commands and drive the cooling element 22 to operate at the corresponding operating level. Further, the control circuit board 40 can adjust the operating level of the cooling element 22 according to the current output power of the ultrasonic module 30 and a set program. For example, if the current output power of the ultrasonic module 30 is low, the power corresponding to the operating level of the cooling element 22 will also be low. In addition, the control circuit board 40 can also adjust the operating level of the cooling element 22 based on the temperature information of the ultrasonic module 30 fed back by the temperature sensing element 50.

[0065] As shown in Figures 1 to 3, in addition to the features of the above embodiments, this embodiment further specifies that: the control circuit board 40 is generally elongated, and the length extension direction of the control circuit board 40 is consistent with the length extension direction of the second cooling section 212.

[0066] The beauty device handle with ultrasonic and cooling technology in the above embodiment further defines the control circuit board 40 as an elongated shape, and its length extension direction is consistent with the length extension direction of the second cooling part 212, which increases the relative area between the second cooling part 212 and the control circuit board 40, improves the heat dissipation effect of the second cooling part 212 on the control circuit board 40, and the elongated control circuit board 40 is better adapted to the space of the mounting cavity 101.

[0067] As shown in Figures 1 to 3, in addition to the features of the above embodiments, this embodiment further specifies that: the first cooling part 211 and the second cooling part 212 are distributed sequentially along the direction of the ultrasonic probe 11 toward the handle 12, and the first cooling part 211 is provided with a relief groove 201, the shape of the relief groove 201 being adapted to the shape of the ultrasonic module 30.

[0068] The beauty device handle with ultrasonic and cooling technology in the above embodiment further defines the distribution of the cooling guide 21 along the length of the beauty gun, so that the first cooling guide 211 is distributed on the side of the mounting cavity 101 close to the ultrasonic probe 11. By having the first cooling guide 211 fit against the inner wall of the ultrasonic probe 11, the temperature of the surface of the ultrasonic probe 11 can be reduced better, so that the user can get a better cooling effect. At the same time, by having a relief groove 201 that matches the shape of the ultrasonic module 30 in the first cooling guide 211, not only can the first cooling guide 211 fit better against the inner wall of the ultrasonic probe 11, but it can also prevent the ultrasonic module 30 from directly contacting the first cooling guide 211, so that the vibration of the ultrasonic module 30 can be transmitted to the cooling element 22 through the cooling guide 21 and affect its normal operation.

[0069] As shown in Figures 1 and 2, in addition to the features of the above embodiments, this embodiment further includes a temperature measuring element 50, which is located in the mounting cavity 101 and close to one end of the ultrasonic probe 11. The temperature measuring element 50 is used to measure the temperature at the ultrasonic probe 11.

[0070] This embodiment provides a skin management system that includes the aforementioned beauty device handle with ultrasonic and cooling technologies.

[0071] The skin management system is a beauty device that integrates massage, cleansing, and product absorption functions. This beauty device can be equipped with multiple beauty guns to achieve different beauty effects; the beauty device handle with ultrasonic and cooling technology described in this application can be one of them.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The above embodiments merely illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
